Grandpa's No-Good Girls (a tale of taboo living)

Grandpa slides his 9 inch cock out of her throat just long enough for her to give an answer. But instead she coughs, saliva sliding out of her throat, forming big gooey strands to Grandpa's cock. She looks up at him with her big brown eyes.

"B...both?"

Grandpa responds with a slap to her face. She gasps.

Then, grabbing her long brown hair, he pulls her close to his face. "You heard what I asked, didn't you Sweetie?"

She's panting, her petite frame is covered in sweat. Her small tits are heaving up and down.

"What did I ask then?" He demands with dominance in his voice.

"You asked if..." she spits, trying to get Grandpa's gray pubic hairs off her tongue. "You asked if I could taste my ass on your cock or if you need to fuck me deeper next time."

"And your answer is?" He sneers as his thick throbbing cock points up at her face.

"Both." She says again quietly. And again she gets a hard slap to the left side of her face. She falls to the ground, but quickly jumps back up to her knees.

"Are you giving Grandpa a shitty answer because you know you'll get slapped?" Grandpa asks.

Sweetie smiles and sheepishly nods. Grandpa goes in for another slap, but holds back. She flinches. He threatens. She flinches. She feels her already-drenched twat only get wetter with the threat of more.

"Ass." Grandpa says, deciding not to reward her with a slap.

Immediately she flips around and drops to all fours. Grandpa steps up, spreads her cheeks and pushes his member deep into her tiny body. Her whole being shudders. He starts to thrust. The sound of flesh slapping against flesh fills the room, which already smells of sex, as if they're engulfed by a thick fog of filth. The excess fat on her thigh would ripple from Grandpa's powerful thrusts, except she has no excess fat on her thigh.

Grandpa grabs that long brown hair again an pulls, arching her back, making sure his meat is as deep inside her as humanly possible.

This all started almost a year and a half ago. She'd graduated high school and declared that she didn't want to go to college. She wanted to be an adult entertainer. Her father said 'No way, never, ever, never." Her mom said "she should do what she wants in life." The ensuing argument broke up the marriage. Dad stomped out, and Grandpa was called in to support since Mom didn't have a job.

Mom could never hold down a job. When she was Sweetie's age, she must have gone through 7 jobs in one year alone. And, Grandpa wasn't dumb. He'd heard the rumors about his daughter, heard that at least twice she was fired for fucking her co-workers, figured she was probably fired from all of the jobs she was ever fired from for that reason.

Grandpa wondered if her husband ever knew what an absolute, total, sex-maniac she was at her core. If he had, he wouldn't have been surprised when his own daughter turned out to be no different.

Anyway, when he moved in, Grandpa decided it was time for everyone to stop being phony, and starting living the life they wanted. Grandpa would support the family and his daughter and her daughter would do exactly what they'd always wanted, which happened to be what Grandpa wanted to.

He pulls his cock from his granddaughter's asshole and she spins around eager to dine on it again. But he holds her back. "Now, did you do what Grandpa asked you today?"

She nods eagerly.

"Tell Grandpa what you did?"
